SHAP values  [1]} provide the additive feature importance measure that adheres to local accuracy, missigness, and consistency.
\(\phi _{\textit {i}} (\textit {f}, \textit {x}) = \sum _{z^\prime \subseteq x^\prime } \frac{\vert z^\prime \vert !(M -\vert z^\prime \vert - 1)!}{M!} [\textit {E}[\textit {f}(z)|\textit {z}_{s}] - \textit {f}(z^\prime \backslash i)]\)
